Title: Improvements in and connected with the Distribution of Air for Pneumatic Hammers.
Inventor: POEL ARMAND VAN DE
IPC: B25D9/18
Filed: 1912-09-27
Granted: 1913-05-22
Abstract: 21,980. Poel, A. van de. July 5, [Convention date]. No Patent granted (Sealing fee not paid). Fluid-actuated gears; slide valves, cylindrical; cylinders, valves co-axial with and moving over ports in. - Relates to pneumatic hammers having cylindrical cupshaped distributing- valves provided with external shoulders upon which the pressure fluid acts constantly, and in which the reversal is effected by fluid acting on the two surfaces at the bottom of the cup. The valve 1 is provided with ports 15, which alternately register with admission and exhaust channels 12, 22 a n d with auxiliary ports 13 and grooves 14 to provide a constant supply of pressure fluid to the interior of the cup on the up-stroke of the piston. Air is supplied to the outer end of the cylinder by a restricted passage 16 and passage 17, and escapes from the inner end by passages 19, 20, 21 and by holes 15, a groove 22, and passages 23, 21. When the piston during its up-stroke passes the port 19, the cylinder fluid passes to the back of the valve 1 and to the exhaust 21, the valve being temporarily locked until reversed by the cushioned fluid entrapped in the valve by the piston 18 passing the ports 15. The reversal of the piston is effected by the cushioned fluid and fluid supplied through ports 13, the forward stroke being completed by the main supply through ports 15. The exhaust from the forward end of the cylinder is continued through ports 17, 24 beneath the shoulder on the valve and the passage 25 to the main exhaust 21. When the piston passes the port 19, the valve is reversed by fluid supplied from the cylinder. The passage 19 may enter the cylinder at two points, or may remain closed during the upstroke of the piston, or may open by a groove into the bore of the valve itself through a passage in the valve.

Granted: 1913-10-16
Abstract: 23,648. Barrows, F. E. Oct. 30, 1911, [Convention date]. Coating - materials; impregnating - compositions.-Fabrics &c. are impregnated or coated with synthetic rubber by adding to them hydrocarbons such as isoprene, erythene, piperyline, diisopropenyl, and the like before or during polymerization, or after polymerization but before removal of by-products. The process may be carried out in several stages, hydrocarbon being added to the fabric &c., and polymerized, the viscous mass thus produced being then added to other compounding-material before the removal of the by-products. To facilitate impregnation, diluents such as benzine may be added at any stage. The products are vulcanized in the usual way.

Abstract: 26,464. Schoenfeld, M. Nov. 18. Embroidery machines.--One or more rows of shuttle races and drivers are arranged so that they may be withdrawn to inoperative positions to permit the remaining row or rows to work over an increased range on the fabric frame. Fig. 1 shows a machine with two rows removed. The driving-bars 11, 13 of the remaining two are coupled by a plain driving- bar 12. In returning the middle rows to operative position, the bar 12 is removed, the top and bottom rows are drawn backwards and the bar 15 is coupled to the bars 11, 13. To secure a correct positioning of all the rows, they are held during the coupling operation by fixed pins 16 which enter sockets in the shuttle race-frames. Fig. 2 shows an arrangement in which the shuttle drivers are coupled up as desired to a driving-rod 12 by pins 17. The bar 12 is mounted in bearings in the machine frame and may be arranged obliquely across the front of the machine to operate obliquely-moving shuttles. In a further construction, the bar 12 is fixed and a lighter driving-bar is mounted to slide in sleeves fixed upon the bar 12.

Abstract: 4347. Scarborough, J. T. Feb. 20. Check or non-return valves.-A check valve particularly adapted for use with pumps for fire-extinguishing apparatus comprises a pair of hinged flaps provided with side flanges and adapted to seat one against the other and against an inwardly curved or inclined fixed seat. In the form shown in Fig. 1, the flaps 2 which are curved and have end flanges 6 are pivoted to links 12, which are in turn pivoted to the casing. The flaps seat against each other at 7 and against the fixed seat at 11, while the end flanges seat against each other at 8 and against the fixed seat at 9. The flaps may be pressed to their seats by springs, or they may be supported by springs or rigidly connected to pivoted arms. The flaps may be straight instead of curved, while the seat may comprise two inclined straight portions. Further, the flaps and flanges may be shaped approximately to form quarter spheres. In the form shown in Fig. 4, the flaps have backwardly - extending flanges 17, adapted to engage recesses in the casing to prevent dirt entering from behind the flaps. Side flanges may be added for a similar purpose. The obturating members may be made of metal, compressed fibre, or vulcanite, and may, if desired, be actuated mechanically. Two or more pairs of flaps may be arranged in the same casing. According to the Provisional Specification, the invention may be applied to a single flap, and facing - strips of rubber or other material may be used between the flaps and the seatings. Specification 18,304/10 is referred to.

Abstract: 641. Buenos Ayres and Pacific Railway Co., [Harte, J. P.]. Jan. 9. Visual outdoor signals.-A semaphore is provided with a route indicator for branch lines and a device for masking the route-indicator when the semaphore is used for the main line. The semaphore is lowered for the main line independently of and without operating the indicator and is lowered for a branch line through the indicator apparatus by means of which, and at the same time, the blank is removed and the corresponding route - indicator is exposed. In lowering the semaphore for a branch road, a selected wire 7 is pulled and the connected lever 5 is turned. This brings a pivoted indicator into view, and by depressing a cross-rod 14, turns a lever 11, so withdrawing the blank 8, and moves a rod 19, so lowering the semaphore. The rod 19 has a pin-and-slot connexion with the lever 17 to permit the direct operation of the semaphore by a wire 21 for main-line working.

Abstract: 9305. Annand, J. W. April 15. Plug couplings.-The plug or socket or both members of a plug-and-socket coupling are formed with a bed portion constituting an integral portion of the conducting-body to which the lead is secured, and one or more complementary bed parts which complete the contour of the plug or socket, are capable only of small movement endways, but otherwise relatively free, and, in the case of a plug, are expanded outwards by a spring so as to afford a good connexion with the socket, or, in the case of a socket, are contracted inwards by a spring on to the plug. As shown applied to a socket, the bed portion B<1>, Fig. 5, has associated with it a complementary portion B substantially semicircular in outline and fitting a semicircular recess in the bed portion. A pin C passing through the two portions prevents relative endlong movement, and a cylindrical casing D, Fig. 1, surrounds the socket and has transverse slits E<2> and a longitudinal slit E<3>, the resulting tongue-portions D<2> of the casing being bent inwards so as to form spring tongues pressing upon the loose element B to afford a spring pressure upon the plug when it is inserted in the socket. The cylindrical ends of the casing prevent lateral movement of the plug. In a modification, the pin C is dispensed with, and endlong movement of the complementary part B prevented by end portions of the main part B<1>. In the form shown in Fig. 9, a complete casing is employed, and a separate spring F, located within an extension, bears upon the complementary part B. The casing and springs may be replaced by one or more helical springs surrounding the parts. Two or more complementary parts may be employed, associated with one fixed part. A plug is shown in Fig. 13 in which the complementary part A<2> is pressed away from the main plug part A<1> by springs H, means being provided for preventing endlong movement of the part A<2>.
